Abstract：China is rich in straw resources,and the conversion of straw into feed is a crucial support for the development of ecological circular agriculture and sustainable development.However,the low utilization rate of straw as feed currently represents a major bottleneck in straw resource utilization.Steam explosion is a green and efficient pretreatment technology,primarily applied to the processing of lignocellulosic biomass(such as wood,straw,and rice straw).It works by separating the cellulose,hemicellulose,and lignin within the raw material's structure,breaking down its recalcitrance barrier,thereby enhancing the conversion and utilization efficiency of the feedstock.Steam explosion does not rely on chemical reagents,avoiding secondary pollution.Compared to traditional pretreatment technologies,it is more environmentally friendly and efficient,holding broad prospects in the field of biomass conversion.This article reviews the key influencing factors such as the process principle,material and equipment parameters of steam explosion pretreatment of straw,and combines the application effect of this technology in animal production,aiming to provide a reference for the efficient utilization of steam explosion in straw feed.
